Question

What is the product of permeability of free space and permittivity?

Answer 1

Hey.

Here is the answer.

With the magnetic permeability established, the electric permittivity takes the value given by the relationship 

c = 1/sqrt(ε0μ0) 

where the speed of light is given by 

c=2.99792458 x 10^8 m/s (exact) 

This gives a value of free space permittivity 

ε0 = 8.854187817 x 10^-12 F/m 

which in practice is often used in the form 

k = 1/4piε0 = 8.987552 X10^9 Nm^2/C^2 = Coulomb's constant 

So, product of permeability of free space and permittivity is 1/c^2.

Thanks.
